How do airplanes fly?
Four forces keep an airplane in the sky. They are lift, weight, thrust and drag. Lift pushes the airplane up. The way air moves around the wings gives the airplane lift.
How are rainbows made?
A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors
Explanation:
Answer:
The contrast in coloration was pivotal to determine if predators attack snakes based on their colors.
It was for studying MIMICRY in snakes.
Assuming all the.snakes were the same the number of attacks will not indicate anything about the effect of the colored rings.
This question on the need for provision of a controlled experiment during experimental investigation. Thus in order to test the effect of a particular condition,another contrasting condition must be provided to determine if the condition under investigation is the actual results obtaned or the influence of other factors in the environment or in the experiment.
The change in the color of the ring is the VARIABLE .In the artificial snake the variable is the presence of this coloed rings against its absence in this snake.
since it changes in the artificial snake

Thermoplastic is known to be a plastic material with a polymer that can be molded above a specific temperature and solidifies upon cooling. Thermoplastics can be remelted or reshaped by heating and they have low melting points. Furthermore, they usually have high concentration of polymers with amorphous structures, the material will have a poor resistance to loads but it will have an excellent elasticity.
Recessive traits are visible in the organisms phenotype as long as TWO recessive traits are present.
